Sanders voted in favor of the 94 crime bill because it included the violence against women act. It was a compromise. He said this on the crime bill:
"...we are dooming today tens of millions of young people to a future of bitterness, misery, hopelessness, drugs, crime, and violence. And, Mr. Speaker, all the jails in the world — and we already imprison more people per capita than any other country — and all of the executions … in the world will not make that situation right. We can either educate or electrocute. We can create meaningful jobs, rebuilding our society, or we can build more jails. Mr. Speaker, let us create a society of hope and compassion, not one of hate and vengeance".
He backed the jets being in Vermont for job creation. It was either Vermont, or in some other state.. He doesn't actually support the military industrial complex. It was just a here, or somewhere else situation.
The toxic waste I'm not really going to defend other than to say it existed, despite what he wanted, and so he did what he thought was best with it. The idea is that it won't spread and contaminate nearly as easily in a drier climate. I will say that I certainly hope the location was a last resort though. I don't know what is normally done with toxic sludge so it's hard to say what should have been done. On the face of it though, I will agree that that is fucked up.
